As with many destinations in the Middle East, Oman is a difficult market to deliver messages to. Numerous filters are in place to block SMS and even legitimate A2P traffic can often be blocked. To prevent filtering, 1s2u is pleased to inform you that we have direct routes into all networks in Oman (MCC=422). In order to guarantee the best quality, 1s2u might make route changes on a temporary basis.
